I have been giving Blu Gyco Flex 3 since his surgery. However, the maintenance dose is 1/2 tablet for his size, and it's a royal pain to chop those suckers in half perfectly.

Anyway, I did some research and I see that Dasuquin is the front runner in this area with the addition of ASU. But, if so, why is it only 800mg of glucosamine? I thought the dogs in Blu's weight range should receive 1,200mg. Am I wrong?

I don't know how the ingredients compare with other brands, b/c I've never used anything other than Dasuquin (except Cosequin, which is the same company and I'm not sure they make anymore). But the stuff has always worked well for my dogs. I gave it regularly to my chocolate lab for several years when arthritis in her elbows and hips got very bad, and I believe it made a big difference in helping to keep her mobile and comfortable. I give it now to Riley, my 10 year old pit bull, to keep the stiffness out of her joints. But this isn't to say that other, less expensive brands couldn't do the same thing... I get a discount on it from my vet, have been satisfied with the results, and just haven't had reason to try anything else.
